I would feed whatever the BP preferred to eat. If I have a choice in the matter, I would choose rats...simply for the personal convenience of feeding one appropriately sized rat, rather than multiple mice to an adult BP. Not to mention that I'll someday be breeding my own rodents and I'd much rather deal with rats than mice.


That's all purely personal choice, though. Whatever your snake eats and whatever you can most readily provide is what is right for you.

There may be some nutritional difference between rats and mice...but since we don't know the nutritional requirements of BPs...those differences don't really mean anything to us. So long as they are getting whole prey of appropriate size...it's all good.
